Was very easy to connect to my monitor and to the Bose headphones. An Original Item came with all the cables reqd. I'm using Aux cable, but optical sound cable is also included in the package. Received the item perfectly on time. Review: Excellent unit that has made my LG C3 OLED TV useable with headphones! - Excellent unit that has made my LG C3 OLED TV useable with headphones! Audio is rock solid and plenty loud enough even without the boost option. In fact the boost introduced a bit of distortion at higher volumes, but luckily I don't need it. The remote for the volume is very responsive and I'm very happy with the unit. It's a very clean, pleasant sound with no noise or buzzing. The only slight niggle is that if I pause any streaming service (Prime, YouTube etc.) the audio does start to break up and go out of sync when I resume the programme. This doesn't happen when using Blu-ray or TV recorder playback - it only seems to be when streaming either from the TV's built in apps or via 4K Firestick. A quick power cycle of the unit always restores the audio perfectly though. (I might plug a USB power adapter into smart socket so I can just ask Alexa to power reset it 😊) It's currently getting its' power from one of the TVs USB sockets. I have tested compatibility with: Shokz Open Dots One Soundcore AeroFit2 Sony WF510 Tozo Openbuds Soundcore Sport X10 Cambridge Melomania 1 All were bought over time to try and get a set of headphones working natively with the LG OLED - none worked reliably with it! All the above headphones worked with other devices and now work seamlessly with the Aventree Oasis Plus 2. Highly recommended! ## Features - [NO LIP-SYNC DELAYS] The Oasis Plus 2’s aptX-Adaptive & aptX-Low Latency support enables high-quality audio at a low latency when used with headphones that also support one or both codecs, ensuring a perfectly synced audio & visual experience at a range of up to 164ft / 50m. - [BOOSTED VOLUMES] Transmitters connected via optical sometimes suffer from low volumes that cannot be adjusted; the Oasis Plus 2 is one of the only transmitters on the market that alleviates this by boosting the volume of optical connections by up to 6dB. - [REMOTE CONTROL] Adjust the volume of your headphones from afar with the included remote control, eliminating the need for manual volume adjustments on devices that don’t have built-in volume controls, such as AirPods or other true wireless earbuds. - [UNIVERSAL COMPATIBILITY] With optical & AUX input options, the Oasis Plus 2 allows you to stream wireless audio from the majority of TVs on the market. - [PASS-THROUGH SUPPORT] The Oasis Plus 2 allows you to bypass audio so you can listen through both an external soundbar & your headphones simultaneously. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DHCKM5T4 | | Audio Input | Optical, 3.5mm AUX | | Audio Output Mode | Stereo | | Audio Output Type | bluetooth | | Battery Weight | 0.03 Grams | | Best Sellers Rank | #575,018 in Electronics ( See Top 100 in Electronics ) #1,101 in Audio & Video Adapters | | Bluetooth support? | Yes | | Box Contents | AUX 3.5mm Audio Cable, Oasis Plus 2 Transmitter, Optical Audio Cable, Remote Control, Type C Power Cable | | Brand | Avantree | | Brand Name | Avantree | | Colour | Black | | Compatibility Options | Bluetooth-enabled devices and TVs | | Compatible Devices | Television | | Connectivity Technology | Optical, AUX | | Connector Type Used on Cable | Auxiliary | | Control Method | Remote | | Control Type | Remote Control | | Controller Type | Remote Control | | Country of Origin | USA | | Customer Reviews | 4.2 out of 5 stars 472 Reviews | | Data Link Protocol | Bluetooth GAP and L2CAP | | Hardware Interface | Bluetooth | | Human Interface Input | Buttons | | Includes Remote | Yes | | Installation Type | wired | | Item Weight | 0.3 Kilograms | | Item Weight Unit of Measure | 0.3 Kilograms | | Lithium Battery Energy Content | 0.04 Kilowatt Hours | | Manufacturer | Avantree | | Model Name | Oasis Plus 2 | | Number of Batteries | 9V batteries required.

It is NOT compatible with HDMI-only TVs, HDMI ARC / eARC audio systems, or TVs that route audio through AV receivers. **Q: Can I connect two Bluetooth headphones at the same time?** A: Yes, you can connect up to two Bluetooth headphones simultaneously to listen to TV audio together. Both headphones share the same audio source. **Q: Can I use a soundbar and Bluetooth headphones at the same time?** A: When using an OPTICAL soundbar, audio can play through both the soundbar and Bluetooth headphones via Optical passthrough. HDMI ARC / eARC passthrough is NOT supported. **Q: Does this work with hearing aids?** A: No. This product will NOT work with hearing aids. If you have Auracast hearing aids and want to listen to TV audio, please choose Avantree Oasis Aura, which is designed specifically for hearing aid use. **Q: How do I control the volume?** A: If your Bluetooth headphones support volume control, you can adjust the volume directly on the headphones. If not, you can easily adjust the volume using the buttons on the transmitter or the included remote control. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality and Original. *by I***T on 1 May 2026* Excellent Quality.
